px-vis-timeseries redraw issue

Hello guys, I'm using the px-vis-timeseries element , the chart can be rendered first time. after I update chartdata, the chart and navigator can't br redrawn , previous graph still exists. my element is like

chart.set is not a function at HTMLElement._formatDataForChart (winddata-view.html:1041) at HTMLElement._observerEffect (loader.html:4664) at HTMLElement._effectEffects (loader.html:4509) at HTMLElement._propertySetter (loader.html:4493) at HTMLElement.setter (loader.html:4572) at HTMLElement. (loader.html:4615) at HTMLElement._notifyListener (loader.html:5132) at HTMLElement. (loader.html:4636) at HTMLElement.fire (loader.html:4345) at HTMLElement._notifyChange (loader.html:4476)

Unfortunately our team doesn't really have the bandwidth to assist with application code. Unless there's a specific reproducible problem in one of our components that we can fix for you, the rest is kind of up to you. I glanced through and didn't see anything wrong with the way you're trying to set the chartData - it does seem a little non-standard to import px-vis-timeseries in your created method instead of just declaring it at the top of the page, but you may have a good reason for it and that may have nothing to do with your issue, I'm not sure.
